Water Fai are a Japanese psychedelic-pop band, formed in Osaka in 2002. These four women dynamically contrast intricate melodies and soft harmonies with violent guitar-noise and electronic effects. They bring a much needed feminine approach to the post-rock genre that is so often dominated by male artists (and their biggest influences) like Mogwai and Tortoise. They bring their own translation of the sentimentality captured best by The Album Leaf and Yo La Tengo.

The band is closely aligned with fellow Osaka-based artists Afrirampo, Jenny on the Planet, Jew's Ear, Middle 9, Suquimaoto..etc. They performed their debut performance in 2002 as the background music for a live painting event.
